21 Burn Blackjack supports up to three simultaneous hands, each settled against the dealer independently. Betsoft's version uses six decks and adds a Burn card option to the ordinary hit-and-stand framework. The title therefore describes a card-game variant, not a reel slot or a live studio table. A natural blackjack is an ace with a ten-value card; drawing several cards to twenty-one is a different hand.
